fast-growing,drought-tolerant trees for Italy (zone 8?)
Hi everyone! I'm making a big garden on my land here in Tuscany, Italy. It's in the foothills of the Appenines, at about 600 meters above sea level,more or less. I have a large, dry area that I would eventually like to "tame" a little; it's covered in yellow broom plants whose flowers attract these very noxious beetles that ruin my roses ,and I was thinking that it would be splendid to put in some real drought-resistant trees in this area, that will eventually help me to shade out the broom and the beetles (both adore sun). The soil is thin and rocky.
I love cypress trees, but don't want to have a monoculture-type thing because of disease risk,so I'd like to mix in some other stuff. Ceratonia siliqua (carob tree) caught my eye,but I fear it might not be hardy in my garden...can anyone comment, or suggest? thanks, bart
